Labour claimed that the SNP's approach to the currency was "a shambles" while the Conservatives said Ms Sturgeon's remarks showed that she was "flimsy and insincere" on the most important of questions.
Sturgeon told BBC Radio Scotland: "I'm not in charge of the Brexit process, I do not know exactly what timescale that is going to follow or how that will unfold". It's about how much money we have to spend on schools and hospitals, what money wages and pensions will be paid in, and will determine how families pay the bills.
Mrs Sturgeon is advocating a referendum for Scotland's secession, although she recognizes that European Union membership would take longer as the country would need to apply for membership.
Ms Sturgeon said the SNP would "protect people form the worst impacts of Tory cuts on soical security".
She said: "We have argued and continue to argue either for it to be scrapped or for fundamental reform of the Common Fisheries Policy".
Ms Sturgeon's predecessor Alex Salmond became First Minister on May 16 2007.
Speaking to activists in South Queensferry, outside Edinburgh, Ms Sturgeon said: "I know we are not flawless". Strengthening Scotland's hand against an unchecked Tory Government which thinks it can just do what it likes and get away with it.
'I think people, if they stop and think about a Scottish Government that's got more powers than any previous Scottish Government, that's got a bigger budget than any previous Scottish Government, what they could have done in 10 years if they hadn't spent so much time trying to rip Scotland out of the United Kingdom and continuing to do so. We haven't got everything right and there is much more work still to do - work to grow our economy, get more people into employment and drive up standards in our schools even further.
"Labour launched its own manifesto this morning, and numerous policies in Labour's manifesto will seem very familiar".
The SNP leader said that if the polls prove right, Jeremy Corbyn's party would be in "meltdown" after June 8 and incapable of standing up to Prime Minister Theresa May.
The Scottish Government put forward proposals at the end of previous year in an attempt to create a bespoke Brexit deal for Scotland - where the vote to remain was 62% - but Ms Sturgeon said they were "dismissed out of hand by the Prime Minister".
"The fact is that they have had the chance to back the SNP's progressive policies - but instead they opposed them tooth and nail". "We have an opportunity in this election to strengthen, not Theresa May's hand, but strengthen Scotland's hand".
"Labour's manifesto gives voters a real choice: a fairer Scotland for the many, not the few; or a Scotland caught between the two extremes of Tory and SNP nationalism".
The SNP leader was asked about the Scottish Government's currency proposals for an independent Scotland at a second referendum.
Scottish Liberal Democrats leader Willie Rennie said: "People are getting exhausted of the SNP and all their promises".
